UITextField-- Can't find keyplane that supports type 5 for keyboard iPhone-Portrait-PhonePad

I have written this code

`

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
     CGRect txtOrigin = [textField frame];
     NSInteger tagvalue = textField.tag +1;
     UIResponder *nextResponder = [textField.superview    viewWithTag:tagvalue];
    if(nextResponder) {
        [self.scrollViewProfile setContentOffset:(CGPointMake(0, txtOrigin.origin.y)) animated:YES];
        [nextResponder becomeFirstResponder];
    }
    else {
        [textField resignFirstResponder];
       [self.scrollViewProfile setContentOffset:(CGPointMake(0, 0)) animated:true];

    }
    if(textField.returnKeyType==9) {
        [self btnSubmit:self.btnOutletSubmit];
    }
    //keyboard method
     [self setEdgesForExtendedLayout:UIRectEdgeNone];
    return  YES;
}`

when execute application in 5s 8.1 it is working properly but with this type of warning or something
